Suppose a right triangle has a
hypotenuse length of 12. If one of
the legs has length 5, what would
the length of the last leg be?
Answer:
See the last two lines below. I don't know which one you want.
Step-by-step explanation:
hypotenuse = 12
One leg = 5
other leg = x Substitute into a^2 + b^2 = c^2
x ^2 + 5^2 = 12^2
x^2 + 25 = 144 Subtract 25 from both sides
x^2 = 144 - 25 Combine
x^2 = 119 Take the square root of both sides
x = sqrt(119)
x = 10.91

The sum of two consecutive integers is 85. Find the integers that satisfy this condition.
Answer choices
A) 1 + 2 = 85
B) x+(x+1)=85
C) x+x=85
D) x+2x=85
Answer:
Option B is correct
Step-by-step explanation:
Let the number be x
Second number = x + 1
Sum = 85
x + x + 1 = 85
2x + 1 = 85
2x = 85 - 1
2x = 84
x = 84/2 = 42
Numbers are 42 and 43
Answer:
B) x+(x+1)=85
Step-by-step explanation:
Consecutive means in a row
Let x be the first integer
x+1 is the next integer
x+x+1 = 85
what is the focus of x2 - 6x + 8y = -9
Answer:
(3, -2)
Step-by-step explanation:
In order to find the focus of a parabola, you must know that the equation of a parabola in a vertex form is y=a(x−h)2+k where a represents the slope of the equation. From the formula, we can see that the coordinates for the focus of the parabola is (h, k+1/4a).

What is the remainder of f(x)=x^3+x^2-9x+23 When divided by binomial X +4
Answer:
The remainder is 11.
Step-by-step explanation:
We are given the polynomial:
[tex]f(x) = x^3 + x^2 - 9x + 23[/tex]
And we want to find its remainder when the polynomial is divided by:
[tex]x + 4[/tex]
We can use the Polynomial Remainder Theorem. According to the PRT, if we divide a polynomial P(x) by a binomial in the form (x - a), the remainder will be given by P(a).
In this case, our binomial is (x + 4) or (x - (-4)). Hence, a = -4.
Then the remainder will be f(-4):
[tex]\displaystyle \begin{aligned}f(-4) &= (-4)^3 + (-4)^2 - 9(-4) + 23 \\ &= 11 \end{aligned}[/tex]
In conclusion, the remainder of the operation is 11.

Find the total surface area.
A. 131.7 mi²
B. 143.4 mi²
C. 198.6 mi²
D. 99.5 mi²
Answer:
B. 143.4 [tex]\text{mi} ^2[/tex]
Step-by-step explanation:
In simple terms, surface area = adding area of all surfaces
This figure has 6 sides.
Surface area = 2 * area of trapezium + 2* area rectangle + area of bottom rectangle + area top rectangle
Surface area = 2 * ([tex](\frac{a+b}{2}) * h + 2* (l*w) + l*w + l*w[/tex])
= [tex]2 * (\frac{3+6}{2} * 2.6) + 2* (8*3) + 3*8 + 8*6[/tex]
= [tex]2 * 11.7 + 2* 24 + 24 + 48[/tex]

From the Question we are told that
Angular diameter [tex]d_a= 30 arcseconds[/tex]
Linear diameter [tex]d_l= 10 cm=0.10m[/tex]
Generally the equation for Linear diameter is mathematically given as
[tex]d_l=\frac{d_a*d}{206265}[/tex]

Help I need an equation and an answer
39. Ashton and James are the same height. If Ashton's height is represented by (6 + 15x) and ames' height is represented by (6x + 42), find the value of x.
Answer:
x = 4
Step-by-step explanation:
Start by setting the two expressions equal to each other, since they're the same height.
6 + 15x = 6x + 42
Subtract 6x from both sides
6 + 9x = 42
Subtract 6 from both sides
9x = 36
Divide both sides by 9
x = 4
An equation is formed of two equal expressions. The value of x is 4.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that the height of Ashton and James are the same height. Also, Ashton's height is represented by (6 + 15x) and James's height is represented by (6x + 42). Therefore, we can write,
Ashton's height = James' height
6 + 15x = 6x + 42
6 + 15x = 6x + 42
15x - 6x = 42 - 6
9x = 36
x = 36/9
x = 4
Hence, the value of x is 4.
